Stability analysis of an offshore wind farm connected to turkish electricity transmission system

Complexing power systems and increasing the amount of renewable energy sources (RES) in the power systems have caused new challenges such as stability, security problem, thus the analysis of stability in the power systems has become very crucial in order to maintain system equilibrium. In this paper, the electricity transmission network with an offshore wind farm (OWF) is modeled. For the grid model, a part of Turkish Electricity Transmission System, near to Gallipoli region, is chosen due to variation of generations and balance between load and generation in this region. In aspect of system stability, the voltage stability analyses with and without an OWF connected to Turkish Electricity Transmission System are demonstrated. Using active power-voltage (P-V) curve and reactive power-voltage (Q-V) curve, the voltage stability analyses has been carried out. In the modeling of the electricity transmission network with the OWF, Digsilent/Power Factory is used as software.
